SEEGIFICATION forming part of Letters Patent 'No. 221,945, dated March 3, 1903.

Application filed lleo'cmher 31, 19 Serial No. 87,888. (l lo moduli) My invention relates to a new and usefulv combined door knob and bell, and is designed to produce a construction which wiil he simpie, cheap, and efieotive.

In the following, with reference to the accompanying drawings, 1 have described a structure embodying my invention, the features thereof being more particularly pointed out hereinafter in the claims...

Figure 1 is a plan view ofi a door-knob ems bodying my invention in place on a door, portions being cut away to showthe constructiou. Fig. 2 is a horizontal view, partly in section, along the line A B of Fig. 3, which is on a slightly-enlarged scale. Fig. 3 is a vertical sectional view along theline G D of Fig. 2. Fig. 4 is a horizontal sectional view along the line E F of Fig. 3., Fig. 5 is a horizontal. sectional view along the line G H of Fig. 3. Fig. 6 is an elevation of certain disconnecting mechanism on an enlarged scale to show the construction and mode of operation more clearly. v

Similar numerals indicate similar parts throughout the several views.'

1 represents a portion of a door, showing: the

.ifsual lock-case having the spring-latch 2. 3 represents the usual door-knob, secured tothe end of spindle 4, which is of the usual con struction and adapted to operate the latch 2; 5 is the base of the other door-knob, which is provided with a shell or bell 6, secured to" the end of spindle 4, the hell 6 being adapted to turn with and operate said spindle in the sameimanner as knob 3. i

Z isia sleeve having a circular periphery and mounted on spindle 4: inside of the bell-knob.

8 is a collar mounted on sleeve 7 and. having a toothed wheel 9 preferably-integral trolled pawl. l2,adapted to hold wheel 9 reverse movement.

13 is a collar on spindle 4, adapted to turn therewith and having an arm 14, hearing a spring controlled pawl 15, adapted to operate wheel 9.

18 is a pin on plate 10, adapted to raise the pawl 15 from the teeth of wheel 9 on a reverse moverneht of the collar 13.

17 is a spring-box having an extended periphery 18, provided with ti -shaped out-out portions 19, said spring-hox hearing also a cog-wheel 20, adapted coast with the spurgear/21011 shaft 22, having its hearings in plate 10 audio a projection 23 from base 5.

Shaft 22 bears at its upper end wheel 24,

adapted to operate the bell-knocker 25, as shown in Fig. 4. Shaft 22 is provided withbuttons 26 26, having rounded tops, as shown, and adapted to hold the end of lever 27 between them.- Button 28 at the lower end of the shaft limits the upward movement of the same. Spring-oontrolled lever 27 is adapted to push shaft 22 upward and whee1s2l and 2% out of contact with wheel and bellknocher 25, respectively. The lever 27 projects through an aperture in base 5 and is cut away at 29 in such manner that when the lever is raised the cut-away portion may be pressed into" a narrow portion of said apertur e and hold the lever up.

@0' is'a spring adapted to be fastened at one end to collar 8 and at the other to spring-box 1'7. Collar 8 is provided with arms 31 31, having fingers 32 32, fitting over a spring fastened to plate 10.

The operation of my device is as follows: The lever 27 being in extended position, as shown in full lines in Fig. 6, so that the wheels 21 and 2d 'are'in contact with wheel 20 a d bell-kuocker 25, the knob 3 is rotated anti 'lockwise, causing the pawl 15 to turn the who i 9, and consequently to wind spring 30 around the collar 8. In the iuitiatory movement the knob should not be turned so far asztouinlatch the door, as by several partial rotations the spring is wound up so fiicient to provide a storage of power. The spring 30 having been thus wound up suiiiciently, the door is opened in the usual fashion by rotating the knob, and as the latch is released the fingers 32 32 release spring 8.3, permitting the spring loox to turn the wheel 20, actuating.- gear 21 and casein-g the hell to ring. Should it he desired to disconnect the bell ringing too , mechanism, the lever 27. may be pushed up four times to one revolution of the springbox. Upon releasing the door-knob from the hand of the operator the latch-spring will cause the spindle to resume its initial position the pawl 15 moving back over the teeth of wheel 9,which wheel is held from any backward movement by pawl 12. Should the person opening the door turn the knob in the wrong direction-that is, clockwise-the pin 16 will lift the pawl 15, so that it will not pass over the teeth of wheel 9, although the bell mechanism will be released as before, and upon releasing the knob the latch-spring will cause the parts to take their initial positions and be ready for further operation. A spring 34 is adapted to hold the pawl 15 against the teeth of wheel 9 when the same is in operation.

The proportions are so arranged that a partial winding of the spring willcause the springbox to rotate sulficiently to ring the bell as desired.

Itis obvious that the form, proportions, and details of construction of the parts may be varied without departing from the spirit of my invention, and therefore I do not restrict myself to the details shown; but

What I claim, and desire to secure by Letters Patent of the United States, is-- f 1. In a device of the class described, the combination of aspindle, two knobs mounted thereon one of said knobs serving as a bell, a boxsurrounding said spindle and having an extended periphery said periphery having cuts or recesses therein, a spring connected to said spindle and to said box, a. stop engaging said cuts or recesses, a. striker, mechanism intermediate said box and striker to actuate the latter, means to move said stop out of engagement with said box to permit the spring to act to cause a series of successive blows of the strikerl 2. In a device of the character described, the combination of a spindle, two knobs mounted thereon one of which serves as a bell, striker mechanism, a' spring to actuate said mechanism secured to said spindle and means to wind said'spring on giving the outer knob a partial rotation in one direction.

3. In a device of the character described, the combination of a spindle, two knobs mounted thereon one of which serves as a bell,:a box surrounding the spindle having therein, a'toothed wheel mounted on said box, a spring secured to said spindle ,and box, a second spring attached to said spindle and adapted to engage said cuts or recesses, a striker and mechanism intermediate thesame and said box to cause the bell to ring when said second spring is released from engagement with said box. 4. In a device of the class described, the combination of a spindle, two knobs mounted thereon one of which serves as abell, a toothed wheel mounted to rotate on said spindle, means to rotate said wheel, a'striker-actuatiug mechanism, a shaft,a.pinion mounted on said shaft and engaging said toothed wheel and a wheel also on said shaft adapted to operate the striker, and means to throw said pinion and wheel out of engagement respec-- tively with said toothed wheel and st iker. 5. In a device of the class descri d, the combination of a spindle, two knobs mounted thereon one of which serves as a bell, a bell ringing mechanism comprising a spring socured to said spindle and means to wind said spring upon a partial rotation of the spindle in, one direction and means to render the wind ing mechanism inoperative it the spindle is turned fully in the opposite direction.

Inwitness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
